CVE-2025-55008: AuthKit React Router: Sensitive auth data rendered in HTML
High · CVSS 7.1 (CVSS 3.1)EPSS 0.39%, 33th percentilePublished Updated Assigner: GitHub_M
Description
The AuthKit library for React Router 7+ provides helpers for authentication and session management using WorkOS & AuthKit with React Router. In versions 0.6.1 and below, @workos-inc/authkit-react-router exposed sensitive authentication artifacts — specifically sealedSession and accessToken by returning them from the authkitLoader. This caused them to be rendered into the browser HTML. This issue is fixed in version 0.7.0.
